Where do you think this crack came from?

[Zet!]

Hey folks,

This morning I went to do some quick chores and noticed that the glass in the rear view mirror has odd reflections starting from the base of the glass (at least from what I saw from inside). When I parked though I noticed some cracks in a sun pattern. I took a picture of it but do you think someone tried to break in (its kind of an odd place to try to break in though) or what do you think could have happened. When touching the glass from outside I don't feel the cracks at all almost like it cracked from inside but the marks look like something hit the glass. Also anyone know how much this might cost to fix? I live in Bay Area, CA and have Tesla Insurance. Needless to say I am super bumbed out about this as I am guessing the glass needs to be replaced which means I have to re-do the tint as well.

I guess i should also add that there isn't anything on the century mode but its usually off when I park in my apartment as I dont have home charging and it eats a bit of the battery.

Sorry for your loss but this thread has such an interesting title that I had to look at it.

My only guess is it coyld be picone as there a big tree next to where I parked last few nights but I didn't see any on the ground and I would think the glass is stronger than that.

Auto glass can appear weak when struck with pointed objects. Pointed objects typically don't require much force at all to crack auto glass. That's why safety glass break devices are merely pointed objects. A little tap will shatter the glass. Granted a pine cone doesn't necesarrily have hardness similar to these devices but most certainty have points. The oriientation of the points of inpact on your window do seem to resemble what might be the points on the "pedals" of a pine cone.

A pine cone? What kind of pine cone weights that much to crack a windshield?

Think about the drop speed if the tree is... lets say 50 to 100 ft. up. Pinecones in my neighborhood can be MASSIVE and feel like incredibly hard wood. I will never park under those trees due to the risk of dents/cracked windows etc.

My property has a lot of tall oak trees. A previous car of mine got hit with a falling acorn and it made a crack just like the one in the photo. Nerd alert:

Energy of falling object

You can do the math, a 7 g red oak acorn falling from a 20 m height.

I doubt even a heavy pinecone could make that kind of glass damage. Just some random idiot hitting your Tesla with something. Shame.

If that's the case there would probably be a sentry activation if the person got close enough. OP, you have Sentry running?

I normally dont at my apartment since it eats quite a bit of battery and I dont have charger anywhere near me aside from supercharger about 2 miles away.
